Due to a problem with quotas (unable to create files apparently due to exceeding quota, although quota was 6GB and usage was nowhere near) I disabled quotas for my file system using the Webmin UI.
Some days later a reboot has failed and I see that /etc/fstab looks like this:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/ / ext3 grpquota,usrquota,rw 0 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
LABEL=SWAP-hda2 swap swap defaults 0 0

I've removedgrpquota,usrquota, from the LABEL=/ line and plan to reboot.
Have I tripped over a problem with webmin?
And does this fix make sense?
